title: [Familial investigations of carriers of Rh 33].
abstract: The erythrocytes of a blood donor (P) showed an unusual pattern with anti-D sera: no agglutination with incomplete sera, and a strong agglutination with 2 out of 5 complete, monoclonal sera. These findings suggested the presence of an Rh 33, which was then confirmed in two external laboratories as the genotyp R0Har. Using anti-e sera, the titer scores of the cells of P were comparable with those of Ee cells but were only half as high as the scores of ee cells. This is consistent with a weak e in R0Har. The red cells of the donor's daughter (T) gave a positive reaction with all anti-D sera, but we observed no or only weak agglutination with several anti-e sera. It is very probable that T is also carrier of R0Har.
